I recently helped a friend move his Smarty 2.6.1 site from one Go daddy shared hosting server (Running PHP4) to a new Go Daddy hosting server with php five. I updated the config.php file and everything seems to be working but I just have one question, when i click on buy now button on homepage it redirects me to registration page, but it shows code on top page. it wasn't their before? Could you advise me what it is. http://www.dasja.co.uk/index.php?page=signup
